A

24 is the upper mandrel-shaft, and 25 is the mandrel carried thereby. 26 is a central bearing for shaft 24, and 27 1S a reduced end. of shaft 24, which passes through the journal-head 16 of bracket 16.

28 1s a leaf-spring secured to bracket 15 and bearing on the reduced end 27 to give the shaft 24 a tendency to move longitudinally. The centering-pin 21 engages a journal-recess in the opposite end of shaf t 24.

29 is a pulley keyed to shaft 24, and 3U is. a band assing around said pulley and around a simi4 `r pulle 31, carried by the shalt 2, by means of whic 1 the shaft 24 will be driven in the same direction and at the same speed as the shaft 2.

32 and 33 are respectively the record and blank mounted, respectively, on the mandrels 25 and 4. By adjusting the position ol' the pin 21 it will be observed that the shaft 24, carrying with it the. mandrel 25 and record 32, can be adjusted longitudinally to insure the proper engagement of the reproducing-stylus therewith.

35 1s a carriage of any suitable construetion clamped at 36 to a guide-tube 37, which operates on the customary guide-rod 38.

39 is the customary spring-ar1n secured to the guidetube 37 and carrying at its forward end the driving-nuts 4U, which are adapted to erwage with the rotary driving-screw ll), and t iereby push the carriage along.

41 is a suitable guide on the front portion of the carriage which engages the front bar 42 of the ordinary phonographmachine. The carriage will therefore slide upon the rod 38 and front bar 42.

45 is a supporting-bar formed with a longitudinal slot 46 and secured to the lug 47 of the carriage 35 by means of' the clampingscrew 48, which passes through the slot 46. The forward end of the bar 45 is formed with a yoke 5U, in which is pivoted a weight 51 on the pins 52.

53 is the reproducing-lever carrying the reproducing sapphire stylus 54 and pivotally connected at its end 55 with the forward end of the pivotally-supported weight 51. The lever 53 has a right-angled extension 53", to which is pivotally connected the recording lever or arm 56, which carries in a suitable socket formed in one end the sap hire ref cording-stylus 57. The forward en of lever 56 rests on a rounded or sharp edge 58 of the supporting-arm 59, which is pivoted in the slidmg block or bracket 60 and is provided with a V or other suitable spring 61 and an adjusting-screw 62 for regulatin its position and adjustin the position ci the styli. The recording-styus 57 is preferably formed of a cylindrical link 57 and an enlarged frusto-conical cutting-head 57h, which may be hollowed out, asl shown in Fig. 5.

The sliding block or bracket 60 is mounted in a suitable slot formed in the bracket 65 and adjusted forward and back in said bracket by the screw 66, which engages a lug on the bracket 60. The bracket 65 is vertically ad'usted on the supporting-arm 67 by means ci the screw 68 and slot 69.

7() is a telltale-reproduer having a diaphragm of any suitable construction from the center of which projects an e re 71.

72 is a thread attached to tie ivot- pin connecting levers 53 and 56 andp passing through the eye 71 and provided at its free end with a small weight 73.

7 4 is a hearing-tube suitably connected to the reprodueer 7U and adapted to have suitable earpieces attached, by means of which the vibrations of the reproducing-arm can be heard and the proper operation of the device detected.

75 is a short rock-shaft suitably journaled in bearings 76 in the carria e and carrying the rock- arms 77 and 78. he rock-arm 77 carries a rod 79, which passes under the spring-arm 39 and is adapted to lift the driving-nuts 40` out of en agement with the screw 1() when the rock-sliiaft 75 is moved.

The rock-arm 78 extends forward and engages under the extension of the pivot-pin 55, which connects the weight 51 and lever 53 and b v reason of such engagement disengages the styli from the record and blank. Keyed to the right-hand end of the rockshaft 75 is an operating-lever 80, pivoted at its lower end 81 to a link 82, which latter has a crooked forward end 83, adapted to extend around a pivot-pin 84.

85 is an operatinginger pivotally mounted upon the pin 84 and connected at 86 with the end of link 82.

87 is a spiral spring attached to lever 8() and link 82 for holding them in the position indicated in full lines in Fig. 2 when all parts are in inoperative icsition or in the position indicated in dotted lines in said figure when the parts are in o eration.

1n Figs. 6 an 7 I have shown a slight modification of the device for operatively supporting the styli. In this form of the device the ivoted supporting-arm 59 has a bifurcatedJ forward end 90, to which the weighted lever 91 is pivoted by means of the pin 92. The reproducing-lever 53 is pivoted to the outer end of the lever 90 and is also pivotally connected to the recording-lever 56, as in the preferred form. The forward end of the record-lever 56 rests on the pin 92.

In Fig. 8 I have shown a further modification, in which the reproducing-stylus 54 and recording-stylus 57 are carried 1n opposite ends of a sin le lever 95, which is ivotally mounted in t e forward end of a balanced wei ht 96, pivoted upon the pin 97. 98 is a hee projecting from the lever 95, and 160 is a thread extending from said heel over a pulai mi and pfovideo with a weight ma', w ich holds the Styli to their work ina inanncr somewhat similar to preferred form.

.In Figs, and 10 I have shown the preferred form of reproducing-stylus, in which a forward end of thevlever 105, carrying the stylus 54, is pivoted to the rear portion 06 by means of a pin 107, which engages in a Suitable socket in the lover portion 106 anda lo `small plate 08. The pivot-pin 107 extends a )proximately at right angles to the tanffcnt oi the cylindrical record at the point which the stylus 54 comes in contact and enables the stylus to readily lind its way into the x 5 groove of the record.

It will be observed that the stylus-supporting lovers 53 and 56 are connected to or Supported from suitable stationary points, which prevent movement in the direction of zo the tangent to the record-blank at the pointl ol contact therewith of the recording-swine. It will also be observed that the two levers are pivoted together in the line approximately perpendicular to the tangent. In recording or duplicating` with my improved machine the tendency of the rotating blank is to move the recording-stylus out of the wax upon an arc drawn from the point of pivot connecting the two levers. Movement in this are is prevented b reason of the weight and the en ragement o the reproducing-st los 'with t e record which is being copie/i The only movement therefore that the stylus can have is in a line perpendicular 3- 5 to the tan ont at the oint of contact of the stylus wit i the recon this being the frcest and best motion for producing a perfect record, because it is least affected by the movement of the record, and the stylus being con- 4o structed and supported to make a clear shearing cutit wi be obvious that a perfect reproduction of the original record will be obtained.

It is to be understood that I do not limit myself to the specific forms ol mechanisms hereinbefore described, but that various inechanical chan es may be made within the scope of the c aims without departing from the spirit of the invention. 5o Having thusfully described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
